Patent number: 9835571Abstract: The detection surface of each of a plurality of detection elements is arranged on an arc along a diffractometer circle (reference circle). This allows each detection element to detect X-rays diffracted by a specimen at the focal position. Because this prevents errors in the X-ray intensity detected by each detection element, more accurate diffraction information can be obtained. As a result, a more accurate analysis can be performed in less time by detecting X-rays diffracted by the specimen using a plurality of detection elements.Type: GrantFiled: October 6, 2015Date of Patent: December 5, 2017Assignee: SHIMADZU CORPORATIONInventors: Tetsuya Yoneda, Takao Marui, Masashi Matsuo

Patent number: 9233729Abstract: A steering damper control apparatus includes an MR damper having an adjustable steering damping force, a suspension pressure sensor that detects a pressure of a front suspension, a command value output unit that determines a damping force command value according to a pressure change rate of the front suspension based on a detection result of the suspension pressure sensor, and a damper driver that causes the MR damper to generate a damping force corresponding to the damping force command value. At a point of time when steering becomes easily shakable, the damping force corresponding to the damping force command value is generated to prevent shaking of the steering beforehand.Type: GrantFiled: May 9, 2012Date of Patent: January 12, 2016Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Yasunobu Harazono, Masashi Matsuo, Nobuo Hara

Patent number: 9120527Abstract: In a steering damper control apparatus, when a command value output unit detects an idle spin of a rear wheel, a damper driver increases a damping force of an MR damper to be higher than a damping force thereof used when the rear wheel is not spinning idly. Therefore, skidding of the rear wheel is prevented to prevent a posture change of a motorcycle. As a result, a driving direction of the rear wheel deviating from a traveling direction is prevented to efficiently use the drive of the rear wheel during traveling.Type: GrantFiled: May 9, 2012Date of Patent: September 1, 2015Assignee: Yamaha Hatsudoki Kabushiki KaishaInventors: Yasunobu Harazono, Masashi Matsuo, Nobuo Hara
